Applicata sled my 21, 1902,

' To alt whom, t may concern/.-

Be it known that I, ROBERT CORNELY, of Paris, France, have invented a new and useful Improvement in Embroiderin g-Machines, which invention is fully set forth in theA following specification.

The present improvements relate to the machine patented under No. 340,422, April 20, 1886, for fastening cords or braids to a fabric by a needle-hook by winding a thread around the cord and the needle and forming from said thread a series of stitches which envelop the cord and secure it to the fabric.

In the accompanying drawings, Figure 1 represents aview of the entire machine; Figs. 2 and 3, views and sections of the central tube below the table of the machine; Figs. 4, 5, and 6 detached views hereinafter to be referred to.

The cord 28 passes from the spool 27 up through the central tube 26, thence through a guide 46 of said central tube and through the stitching-disk 17, which projects through an opening in the cloth-plate 50. 'On this central tube 26 turns the revolving tube threadcarrier 4, through which a passage 45 has been made for the thread 5, which passes from the spool 44 through the revolving tube 4 and through the stitching-disk 17 to the cloth-plate. The'thread-carrier 4 receives its revolving motion from main shaft 47 through the wheels 6 and 7, 8 and 9, i12, 13, and 14, 15 and 16 and its turning motion from the crank-handle 41 of the machinethrough wheels 18 and 19, 48 and 49, 11 and 10, 13 and 14, and 15 and 16. The stitching-disk 17 receives its turning motion from the crankhandle 41 by means of wheels 18 and 19 and 24 and 25, which latter is secured to a tube 30, which supports the stitching-disk 17. The spool-holder 42 of the cord 28 receives lits turning motion from the crank-handle 41 by means of 'the wheels 18 and 19, 20 and 21, 22 and 23, 40 and 29, which latter is secured to a sleeve 50, to which the spool-holder 42 is secured. The' needle38 is connected with the crank-handle 41 in the manner well known in universal-feed machines, which needs no new description. Thus all the organs of the stitching apparatus execute the motions already described in Patent No. 340,422, as well as for producing the stitch, as for turning serial No. 116,456. J (No moana with the handle in conformity with the universal feed of the embroidering-machine.

The machines used heretofore have well executed their Work when it was done on large patterns or on straight lines, but upon work- 'iug on very small designs or sharp angles,

where a very rapid turning of the crank-handle isrequired, and consequently also of the stitch-producing organs, the machine produced frequently miss-stitches, for the reason that the revolving thread 5 passed frequently in such sharp turnings below the point of the needle before its hook could seize it for producing the stitch. The object of the present application is the arrangement of certain devices in order to prevent said miss-stitches.

The revolving thread-guide tube 4 is secured in the frame 35 against longitudinal motion by a washer 34 and bya cam 31, which leases 'cam 32, and then spring 33 presses' cam 32 and tube 26 upward.` A thread-catcher 36 is secured to the upper end of tube 26, and

:when the latter is in its highest position it extends into a recess 3 7 of the stitching-disk 17,

as shown in the positions of Figs. 3 and 4.

@When the needle-hook 38 commences its descending motion, the tube 26, with its threadcatcher 36, stands in its highest position, Figs. 3 and 4, and the rotating thread-carrier 4 winds its thread around the thread-catcher 36 instead of winding it directly around the needle, and when the latter has descended a certain length the tube 26, with its threadcatcher 36, are pressed downward into the position shown at Figs. 2 and 5, and the thread 5 is released and by the continuous rotating motion is woundin an infallible manner around the needle, so that its hook cannot miss seizing it, and thus any dropstitches are impossible, even when executing the sharpest turns of the crank-handle.

The machine shown and described works with the needle above the cloth-plate and the revolving thread-carrier and cording-tube below the table; but this automatic thread- IOO catcher may equally well be applied to the machine shown and described in Patent 575,027, where the organs are inverted-t'. e., where the needle-hook works from below the table upward and where the revolving threadcarrier and the cording-tube are above the table.

It is evident that instead of one cord two cords 28, wound on two spools 27, can by the same process be secured to the fabric one alongside the other.

I claiml. The combination ofacloth-plate, ahookneedle, operating from one side of the clothplate, a cord or braid guide, a rotary threadcarrier for wrapping a thread about the cord and to engage it in the needle-hook, and a thread-catcher, all on the other side of the cloth-plate, the thread-catcher operating to engage and hold the thread until the needle is projected through the cloth-plate to a position to insure engagement of the thread with its hook and then to release the thread.

2. The combination ofa cloth-plate, ahookneedle, operating from one side of the clothplate, a cord or braid guide, a rotary threadcarrier for wrapping a thread about the cord and to engage it in the needle-hook, and a thread-catcher, all on the other side of the cloth-plate, the thread-catcher operating to engage and hold the thread until the needle is projected through the cloth-plate to a position to insure engagement of the thread with its hook and then to release the thread, and mechanism for controlling the direction of feed and for turning the stitch-forming elements accordingly.

3. The combination of a cloth-plate,a hookneedle operating from above the same, cord or braid guiding means below the cloth-plate, a rotary thread-carrier below the cloth-plate for winding a thread around the cord or braid and to introduce it into the needle-hook, a movable thread-catcher below the cloth-plate, and thread-catcher-operating means for moving the thread-catcher into position to engage and hold the thread until the needle is projected through the cloth-plate to a position to insure engagement of the thread with its hook and for then withdrawing the threadcatcher to release the thread. t

4:. The combination of a cloth-plate,a hookneedle operating from above the same, cord or braid guiding means below the cloth-plate, a rotary thread-carrier below the cloth-plate for winding a thread around the cord or braid and to introduce it into the needle-hook, a movable thread-catcher below the cloth-plate, and thread-catcher-operating means for moving the thread-catcher into position to engage and hold the thread until the needle is proj ected through the cloth-plate to a position to insure engagement of the thread with its hook and for then withdrawing the thread-catcher to release the thread, and mechanism for controlling the direction of feed and for turning the stitch-forming elements accordingly.

5. The combination of a cloth-plate, a hookneedle operating from above the same, cord or braid guiding means below the cloth-plate, a rotary thread-carrier below the cloth-plate for winding a thread around the cord or braid and to introduce it into the needle-hook, a thread-catcher below the cloth-plate consisting of an upright pin or projection, threadcatcher-operating mechanism for elevating said pin until its upper end engages in a recess under the cloth-plaie in which position it acts to engage and hold the thread until the needle is projected through the clothplate to a position to insure engagement of the thread with its hook and for lowering said pins to release the thread.

6. The combination of a cloth-plate, a hookneedle operating from above the same, cord or braid guiding means below the cloth-plate, a rotary thread-carrier below the cloth-plate for winding a thread around the cord or braid and to introduce it into the needle-hook, a thread-catcher below the cloth-plate consisting of an upright pin or projection, threadcatcher-operating mechanism for elevating said pin until its upper end engages in a recess under the cloth-plate in which position it acts to engage and hold the thread untilthe needle is projected through the cloth-plate to a position to insure engagement of the thread with its hook and for lowering said pin to release the thread, and mechanism for controlling the direction of feed and for turning the stitch-forming elements,including the threadcatcher, accordingly.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ROBERT CORNELY.
